Ant and warthog do not universally evoke negative emotion. In many cultures ants are in fact associated with creatures that work hard, some people when they hear ants they think of the emergent behavior their colonies manifest. Warthog is more of a neutral term. Hearing that word gives me neither good or bad emotion, so it really depends on the context you use it. "Cockroach" on the other hand, like i said, I know of absolutely NO one who would get positive emotion upon hearing that word. Just like "rape", or "nazi" don't evoke positive emotion for anyone.
